Targeting APRIL in the treatment of glomerular diseases.

A proliferation-inducing ligand (APRIL) is a key member of the tumor necrosis factor superfamily of cytokines and plays a central role in B-cell survival, proliferation, and Ig class switching. Recently, there has been increasing interest in the role of APRIL and the related cytokine B-cell activating factor in several glomerular diseases, because of their importance in the above processes. The therapeutic inhibition of APRIL represents a potentially attractive immunomodulatory approach that may abrogate deleterious host immune responses in autoimmune diseases while leaving other important functions of humoral immunity intact, such as memory B-cell function and responses to vaccination, in contrast to B-cell-depleting strategies.

Primary retroperitoneal tumor: mucinous cystoadenocarcinoma.

Primary retroperitoneal mucinous cystadenocarcinomas (PRMCs) are extremely rare tumors with limited understanding of their pathogenesis and biological behavior. We describe a case of a 50-year-old female patient who underwent surgical treatment. The patient had a history of previous surgeries for mesenteric mucinous cystadenoma, without evidence of recurrence.

Binary Soong grading as a predictor for flexor pollicis longus tendon rupture after distal radial fracture fixation: a retrospective study.

This retrospective cohort study evaluates the concordance between Soong grades classified from radiographs and computed tomography (CT) scans and whether a Soong grade ≥1 is associated with flexor pollicis longus (FPL) injury and reoperation incidence. We included 181 patients with 185 dorsally displaced distal radial fractures treated with anterior locking plates. For the analysis of binary Soong grades, grade 0 was compared with grades 1 and 2.

Low muscle mass index is associated with type 2 diabetes risk in a Latin-American population: a cross-sectional study.

Objective: Diabetes mellitus is a growing disease with severe complications. Various scores predict the risk of developing this pathology. The amount of muscle mass is associated with insulin resistance, yet there is no established evidence linking muscle mass with diabetes risk.

Complications of intraosseous administration of vancomycin in total hip arthroplasty.

Introduction: The incidence of periprosthetic joint infection (PJI) in hip surgeries has significantly decreased thanks to intravenous (IV) antibiotic prophylaxis. However, in patients colonized with methicillin-resistant Staphylococcus aureus (MRSA) or those at risk of colonization, it is necessary to include vancomycin in the prophylaxis. Intraosseous administration of vancomycin could enhance its effectiveness in total hip arthroplasty (THA).

Impact of high-flow oxygen therapy via high velocity nasal insufflation on diaphragmatic thickening fraction in healthy subjects.

Objective: The primary objective of this study was to evaluate the impact of high-flow nasal cannula oxygen therapy [HFNC] on the diaphragm thickening fraction.

Cardiovascular disease is a worldwide health problem affecting millions of people and leading to high rates of mortality and morbidity. There is a well-established association between cardiovascular disease and circulating cholesterol.

Different tracers for sentinel node detection in gynecologic oncology.

Purpose Of Review: In the past decade, sentinel lymph node (SLN) mapping has progressively substituted full lymphadenectomies in gynecologic oncology. In this article, we review the most relevant and the latest literature on this topic.

Recent Findings: In endometrial and cervical cancer, the current evidence further support the value of indocyanine green (ICG) as tracer of choice for SLN mapping.

Electrodiagnostic subtyping in Guillain-Barré syndrome patients in the International Guillain-Barré Outcome Study.

Background And Purpose: Various electrodiagnostic criteria have been developed in Guillain-Barré syndrome (GBS). Their performance in a broad representation of GBS patients has not been evaluated. Motor conduction data from the International GBS Outcome Study (IGOS) cohort were used to compare two widely used criterion sets and relate these to diagnostic amyotrophic lateral sclerosis criteria.

Seven-day antibiotic therapy for Enterobacterales bacteremia in high-risk neutropenic patients: toward a new paradigm.

Purpose: Data on short courses of antibiotic therapy for Enterobacterales bacteremia in high-risk neutropenic patients are limited. The aim of the study was to describe and compare the frequency of bacteremia relapse, 30-day overall and infection-related mortality, Clostridiodes difficile infection and length of hospital stay since bacteremia among those who received antibiotic therapy for 7 or 14 days.

Gene expression assays (GEAs) can guide treatment for early-stage breast cancer. Several large prospective randomized clinical trials, and numerous additional studies, now provide new information for selecting an appropriate GEA. This systematic review builds upon prior reviews, with a focus on five widely commercialized GEAs (Breast Cancer Index®, EndoPredict®, MammaPrint®, Oncotype DX®, and Prosigna®).

Lack of correlation between central venous minus arterial PCO to arterial minus central venous O content ratio and respiratory quotient in patients with septic shock: A prospective observational study.

Objective: Central venous-arterial PCO to arterial-central venous O content ratio (PCO/CO) is commonly used as a surrogate for respiratory quotient (RQ) and tissue oxygenation. Although PCO/CO might be associated with hyperlactatemia and outcome, neither the interchangeability with RQ nor the correlation with conclusive variables of anaerobic metabolism has never been demonstrated in septic shock. Our goal was to compare PCO/CO and RQ in patients with septic shock.

Agalsidase alfa long-term effect on left ventricular hypertrophy in Fabry disease.

Introduction: Fabry disease (FD) is an X-linked lysosomal storage disorder affecting glycosphingolipid metabolism. Most FD patients have cardiac involvement, mainly manifested as left ventricular hypertrophy (LVH), leading to early death due to complications (arrhythmias, valvular disease, vascular involvement). Early initiation of enzyme replacement therapy (ERT) before fibrosis development has been associated with better cardiac outcomes in terms of left ventricular mass index (LVMI) and functional parameters.
